Introduction to Wireless Power Transmission
Wireless power transmission, also known as wireless energy transfer, is the process of transferring electrical energy from a power source to a device without the use of wires or cables. This technology has been around for several decades, but it has only recently gained significant attention and investment. The idea of wireless power transmission may seem like science fiction, but it is a reality that is being developed and implemented by companies and researchers around the world.
History of Wireless Power Transmission
The concept of wireless power transmission dates back to the 19th century, when Nikola Tesla experimented with the idea of transmitting energy wirelessly over long distances. However, it wasn’t until the 2000s that the technology started to gain traction. In 2007, a team of researchers from the Massachusetts Institute of Technology (MIT) demonstrated the ability to transfer energy wirelessly over a distance of several meters. Since then, the technology has advanced significantly, with companies like WiTricity and Qualcomm developing commercial-grade wireless power transmission systems.
How Wireless Power Transmission Works
Wireless power transmission works on the principle of electromagnetic induction. A transmitter coil is used to generate a magnetic field, which induces an electromotive force (EMF) in a receiver coil. The receiver coil is connected to a device, such as a smartphone or a laptop, which uses the induced EMF to charge its battery. The process is similar to how a transformer works, but instead of using a physical connection, the energy is transferred wirelessly.
